At the drying process with humidity control, the air humidity is measured by an absolute air
humidity sensor. The graph shows the absolute air humidity in function of time.
When a drying cycle is started, the air humidity will go up quickly as the heating system starts
up, then the air humidity will decrease bit by bit.
The dryer computer humidity sensor measures this value and calculates the corresponding
residual humidity of the linen.
The residual humidity is the remaining amount of water in wet linen compared with it's dry
equivalent.
When the linen is taken out a washing machine :
- a high extraction speed results in about 50 % residual humidity
- a low extraction speed results in about 70 % residual humidity
At the drying cycle (humidity control) there is shown on the display :
H - - : The residual humidity is above 30 % (the linen is wet)
H XX : The residual humidity value is below 30% (the linen gets dry)
Above 30% residual humdity, the linen is so wet that there is no accurate measurement.
(for this reason there is not shown a value on the display but just two dashes)
It can take 10 to 40 minutes depending the amount of load and how wet the linen is before
the Residual Humidity Value is shown on the display.
Just for informative purposes, the time on the display is counting up as indication for the complete
drying time.
The default programmed value for residual humidity of linen is 5%.
ATTENTION
AT A RUNNING DRYING CYCLE, BEST IS NOT TO INTERRUPT THE DRYING CYCLE BY OPENING
AND CLOSING THE DOOR AS THIS DISTURBS THE HUMIDITY CONTROL MEASUREMENT
WARNING !!!
CERTAIN FABRICS CAN GET DAMAGED WHEN DRYED UNTIL A RESIDUAL
HUMIDITY OF 0%. (BONE DRY)
CERTAIN FABRICS GET ELECTROSTATIC CHARGED FOR A RESIDUAL
HUMIDITY BELOW 5% (WHICH SHOULD BE AVOIDED).
ATTENTION
THE HUMIDITY CONTROL SYSTEM IS NOT MADE TO RUN WITHOUT LOAD OR WITH A VERY
SMALL LOAD. THE SYSTEM CAN ONLY FUNCTION IN A NORMAL WAY WHEN THERE IS
SUFFICIANT EVAPORATION TO BE MEASURED BY THE AIR HUMIDITY SENSOR.
